2. What are CRUDE Drugs?
▪ Crude drugs are plant, animal or their parts which after collection
are subjected only to drying or making them into transverse/
longitudinal slices pieces or peeling them in some cases. They
exist in natural form.
▪ The crude drugs are divided into different groups according to the
chemical nature of their most important constituent present in the
drug to which the pharmacological/therapeutic activity of drug is
attributed.
▪ Certain drugs are found to contain alkaloids and glycosides
(Cinchona), Fixed oil and volatile oil (Nutmeg) of equal importance
together

3. Standardized Extraction
procedures for crude drugs
CLASSES OF PREPARATIONS KNOWN AS
DECOCTIONS, INFUSIONS, FLUID EXTRACTS,
TINCTURES, PILULAR (SEMISOLID) EXTRACTS
AND POWDERED EXTRACTS
SUPERCRITICAL FLUID EXTRACTION (SFE)

6. Extract Types
Standardised Extracts
are adjusted within an acceptable tolerance to a given
content of constituents with known therapeutic activity;
standardization is achieved by adjustment of the extract
with inert material or by blending batches of extracts.
Quantified Extracts
are adjusted to a defined range of constituents;
adjustments are made by blending batches of extracts.
Other Extracts
are essentially defined by their production process (state
of the herbal drug or animal matter to be extracted,
solvent, extraction conditions) and their specifications.
